DYEING-MACHINE.

Specification of Letters Patent.

Patented May 14, 1918.

Application filed Milly 16, 1917. Serial No. 168,922.

To all whom it may concern:

Be it known that I, HOWARD M. DUDLEY, a citizen of the United States,and a resident of Philadelphia, in the county of Philadelphia and Stateof Pennsylvania, have invented certain new and useful Improvements inDyeing-Machines, of which the following is a specification.

My invention refers to dyeing machines and refers-particularly to amachine suitable for the dyeing of worsted top and warp balls.

One object of my invention is a device whereby worsted top, warp ballsand similar fibers may be thoroughly and evenly dyed and treated withliquids and air.

Another object of my invention is a device whereby fibers in thecondition stated above may be dyed and treated without injury to thefiber.

Another object of my invention is a device whereby fibers in thecondition stated above may be readily and rapidly packed into dyeingchambers and compressed into a form suitable for even penetration.

Another object of my invention is a device whereby a considerable numberof balls, tops, &c. may be dyed equally.

These and other objects of my invention will. be evident upon aconsideration of my specification and claims. I

The dyeing of worsted tops, Warp balls and similar fibers presentsseveral diflioulties which must be overcome in order to produce even andsatisfactory results.

On account of the physical condition of the fibers, they must not bedisturbed during the dyeing operationbut must be retained in theiroriginal untangled condition.

On account of the shape of the tops or balls, satisfactory results havenot been obtained by placing them in layers each layer comprised of anumber of tops or balls as when compressed, channels or openings areformed between the tops and balls, as it is not possible to compressthem all into a uniform mass for the passage of the liquid. I haveovercome all of these ditficulties and the device of my invention willdye fiber forms of this character evenly and completely.

In the drawings illustrating several modifications of my device similarparts are designated by similar numerals.

Fig. 8 is a top-plan view of a portion of a modified form of aforaminous plate.

Fig. 9 is a developed side elevation of a portion of the foraminousplate of Fig. 8.

The device comprises a receptacle formed of the cylindrical member 10,attached to the conical member 11 by means of the bolts 12, 12 and theconical member 11 is attached to the pump chamber 13 of the pump 14 bymeans of the bolts 15, 15. The top portion of the receptacle has anoverflow pipe 16, discharging into the liquor tank 17. The lower portionof the tank 17 is connected to a pipe 18 having the valve 19, the pipe18 being connected to the pipe 20 which in turn is connected to the pumpdelivery pipe 21. The pipe 21 is connected to the pipe 22 having a valve23. The pipe 22 is connected with pipe 24 having the valve 25. The pipe22 is connected with a dye dissolving tank not shown, and the pipe 24 isconnected with a source of fresh water supply. The pump chamber 13carries the pipe 26 with the valve 27.

Within the cylindrical member 10 of the receptacle is fixedly positioneda series of cylindricalv fiber containers each comprised of theimperforate side 28 and the foraminous bottom 29. Adjacent to each fibercontainer is a port 30, extended upwardly into a testing device 31,having the valve 32 and the revoluble pipe 33. Each testing devicecomprises an im'perforate side, a torami nous top and a for-aminousbottom similar and proportionate to those of the dyeing chambers.Adjacent to each fiber container is a port 3st extended upwardly intothe pipe 35 comprising the thermometer 36. Situated slidably within eachfiber container is a foraminous top 37 (Fig. 5) and slidable within thefiber container and capable of abutment upon the top 37 is the annularmember 38 with its extended ring portion 39. By means of the wing screwbolts 40, 40 which extend through the ring 39 and thread into holes inthe extended portion 41 of the wall 28, the member 38 may be fixed inany predetermined position within the receptacle.

The foraminous top 37 and the foraminous bottom 29 are of the sameconstruction and consist of a series of concentric rings 81, 81 havingupwardly and downwardly extended triangular members s2, The rings 81, 31are maintained in position by the cross menbersa3, L3 integral with therings 81, 81.

Within the conical member 11, are a series of spaced nested conicalmembers it, let supported by the supporting cross-members 45., 45.

The fiber containers 28, 28 are positioned between the outer wall. 10and the inner wall 46, and the space included within the wall 46 isclosed at the bottom by the member l7 and at the top by the member t8,the latter being slightly below the outlet -19 of the overflow pipe 16.The member 48 extends completely across the receptacle 10, slightlybelow the tops of the fiber containers 28, thus forming a chamber in theupper portion of the receptacle capable of receiving the liquid whichhas passed through the fiber containers, the thermometer, and thetesting devices.

Within the space between the bottom foraminous plates 29, 29 and theupper extremities of the nested conical members t4 n is a perforatedsteam pipe 50.

In the modification shown in Figs. 7, 8, 9. the receptacle is square andcarries .a series of four fiber carrying chambers, with testing portsand thermometer ports, the general construction being the same as shownin the other figures, except that in this case the two foraminous plates29 and 37 are comprised of a series of spaced nested rings 51, 51supported by the cross-members 52, 52, the latter carrying upwardly anddownwardly extended triangular members The operation of the device is asfollows: The pipe 33 is revolved into the position 33 the member 38 andthe foraminous top 37 are removed and the warp balls 51-, 54 insertedinto the fiber container, the foraminous top 37 is then placed upon theupper warp ball, the member 38 inserted within the fiber container andthe top 37 pressed downwarc'lly, by means of the member 38 operatedthrough the win screw bolts i0, l0, thus compressing the arp balls intothe desired condition. The pipe 33 is revolved into the position 33. Thepump 14 is started and a dye solution allowed to enter the pump throughthe pipes 21, :21, the valves 19, 25 and :27 being closed. When theproper amount of dye liquor has been introduced, the valve 23 is closedand the valve 19 opened. The liquor now passes from the tank 17 into thepump 141 and is forced upwardly between the nested conical members 44:,4A through the space immediately above where it is maintained at aproper temperature by the steam pipe 50, and then upwardly through theforaminous bottom 29, the warp balls 5%, 5a, the foraminous top 37 andthen through the overflow pipe 16 back into the tank 17. A portion ofthe liquid also passes upwardly through the port 30 into the testingdevice 31, containing fiber, and from thence outwardly into thereceptacle and back into the tank 17 through the overflow pipe 16.Liquid also passes upwardly through the pipe 35 carrying the thermometer36, thus recording the tempera ture of the liquid. By closing the valve32 the condition of the fiber may be determined by examining that withinthe testing device 31 without interrupting the operation in the largerdevice.

When the dyeing operation is completed the valve 19 is closed and thevalve 27 is opened, thus draining all of the liquid from the devicethrough the pipe 26. Valve 27 is then closed and valve 25. opened, andfresh water for washing purposes is delivered to the pump 14 through thepipes 24, 21 and forced upwardly through the device. After properwashing the valve is closed and valve 27 opened, draining the water fromthe receptacle. If it is desirous of-treating the fiber with air, foroxidizing, drying or other purposes, the pump lat is stopped and airforced through the pipe 26, the receptacle, and the fiber containedtherein.

I do not limit myself to the particular size, shape, number orarrangement of parts as described and shown, ,all of which may be variedwithout going beyond the scope of my invention as described and claimed.
